History

Duncan P. N. Exon Smith 22e6b1863e SourceManager: Fix an SLocEntry memory regression introduced with FileEntryRef `4dc5573acc` added `FileEntryRef` in order to help enable sharing of a `FileManager` between `CompilerInstance`s. It also added a `StringRef` with the filename on `FileInfo`. This doubled `sizeof(FileInfo)`, bloating `sizeof(SLocEntry)`, of which we have one for each (loaded and unloaded) file and macro expansion. This causes a memory regression in modules builds. Move the filename down into the `ContentCache`, which is a side data structure for `FileInfo` that does not impact `sizeof(SLocEntry)`. Once `FileEntryRef` is used for `ContentCache::OrigEntry` this can go away. Differential Revision: https://reviews.llvm.org/D89580 Radar-Id: rdar://59908826		2020-10-26 15:38:13 -04:00

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
